Great!

Are you also planning to do the removal of the pg_listener catalog?
There were some ideas on how to do this, but nothing thoroughly
designed.

Neil Conway talked about using SLRU as a mechanism for storing listeners
and messages.  Maybe you can find that discussion in the archives.  Part
of it was via IRC though, and I don't remember how much of it was.  So
details on the archives may be thin.
